Description
The PS Harmonic Estimator (Real, Imaginary) block measures real and imaginary parts of a single frequency component (harmonic) of a periodic signal.
A signal is periodic if it completes a pattern within a measurable time frame, called a period, and repeats that pattern over identical subsequent periods. The signal base frequency is the number of periods per second.
The block accepts a physical signal with one or more harmonics present. It outputs the real and imaginary parts of the signal for the selected harmonic. Untyped physical ports facilitate unit propagation. The output signals at both ports have the same physical unit as the input signal.
To obtain meaningful results, run the simulation for at least one full time period of the signal.
